The most common causative organisms of acute bacterial meningitis are Streptococcus pneumoniae (also called Pneumococcus), Streptococcus agalactiae, Neisseria meningitidis (also called Meningococcus), and Listeria monocytogenes. 19,20 Relationship between colonial morphology and adherence of Streptococcus pneumoniae. D R Cundell , J N Weiser , J Shen , A Young , E I Tuomanen Infection and Immunity Mar 1995, 63 (3) 757-761; DOI: Se hela listan på wwwnc.cdc.gov Se hela listan på frontiersin.org Streptococcus pneumoniae is a Gram positive cocci, typically lancet shaped and occurs singly, in pairs (diplococci) or in short chains. Streptococcus pneumoniae in Gram Staining. Main diseases caused by Streptococcus pneumoniae: Bacterial pneumonia: Most common bacterial cause, especially in infants and elderly. 2010-05-01 · Streptococcus pneumoniae (the pneumococcus) colonizes the human nasopharynx and can also cause diseases, including otitis media, pneumonia, bacteraemia, and meningitis. The organism produces a range of colonization and virulence factors, including the polysaccharide capsule, surface proteins and enzymes, and the toxin pneumolysin (PLY).

Streptococcus pneumoniae morphology

They are non-sporing and non-motile bacteria. May have pili for adherence. They are 0.5 x 1.25 µm in diameter. They are mostly found in pairs (diplococci). Also In throat swabs Streptococcus pneumoniae can occur in its avirulent form (oropharyngeal carriage of pneumococci is common and they are considered to be part of normal flora). The colonies are only 0.5-2 mm in diameter, surrounded by zone of alpha-hemolysis and due to autolysis, often develop a dimpled rather a craterlike appearance. Se hela listan på microbewiki.kenyon.edu Streptococcus pneumoniae, or pneumococcus, is a Gram-positive, spherical bacteria, alpha-hemolytic (under aerobic conditions) or beta-hemolytic (under anaerobic conditions), facultative anaerobic member of the genus Streptococcus.

Usually, they are seen as pairs of cocci (diplococci), but they may also occur singly and in short chains. When cultured on blood agar, they are alpha hemolytic. Streptococcus pneumoniae is a Gram positive cocci, typically lancet shaped and occurs singly, in pairs (diplococci) or in short chains..
